TL;DR: The writer finds an unusual basidiomycete in a wooded area near his residence in the Punaauia District of Tahiti, which is believed to occupy a position of primitiveness in the Ceratobasidiaceae, indicating a phylogenetic connetcion of this family with the Tremellaceae.
Abstract: IN JUNE of 1956, while engaged in a study of the fungi of the Society Islands, the writer found an unusual basidiomycete in a wooded area near his residence in the Punaauia District of Tahiti. The fungus appeared as a thin, gray, waxy-pruinose growth on the bark of a dead limb of the mango tree. A microscopic examination revealed basidia with four long, stout sterigmata typical of the genus Ceratobasidium. Furthermore, the basidiospores, like those of the latter genus, were found germinating by repetition. On the other hand, the new fungus differs markedly from all known species of Ceratobasidium in having gloeoeystidia and incompletely septate basidia. If the basidium is viewed apically after the septa have appeared, the cruciform arrangement of the septa, so characteristic of the tremellaceous basidium, may be observed, and the basidium appears to be 4-celled (fig. 8). But when the basidium is viewed laterally the septa are found to be incomplete below. -Occasionally a septum seems to extend all the way through the basidium or nearly so, but a change of focus always shows it to be interrupted in some area (fig. 5, 6). The septa usually begin to appear just before the sterigmata start developing (fig. 2). They may persist during spore formation (fig. 10, 13, 14) but frequently may not be detected at this time (fig. 11, 12, 15, 16), and it is probable that in a majority of the basidia they disintegrate by the time of spore discharge. Possibly they do not appear at all in some basidia. To the writer's knowledge no such fungus has been previously reported. It is hereby described as a new species, and a new generic name is proposed for it. The new genus is believed to occupy a position of primitiveness in the Ceratobasidiaceae, indicating a phylogenetic connetcion of this family with the Tremellaceae.

TL;DR: During a recent survey of the lower basidiomycetes of the Society Islands, five different species belonging to the Tulasnellaceae were found in Tahiti and the nearby island of Moorea, two of them not previously described so far as can be determined.
